The Vanishing of Ethan Carter can be played without launcher from:

TheVanishingofEthanCarter\Binaries\Win32\AstronautsGame-Win32-Shipping.exe
or
TheVanishingofEthanCarter\Binaries\Win64\AstronautsGame-Win64-Shipping.exe
or
TheVanishingofEthanCarter\Binaries\Launcher.exe

The Vanishing of Ethan Carter Redux can be launched directly from executable (EthanCarter.exe)

Edit: It seems easiest to just launch The Vanishing of Ethan Carter from TheVanishingofEthanCarter\Binaries\Launcher.exe. It automatically launches AstronautsGame-Win64-Shipping.exe for me, and probably 32-bit executable if you're on 32-bit Windows. You also get some more advanced graphics options there than in-game.

Loop Hero can be launched directly from executable.

An update to this: Epic's servers had problems earlier today, and nobody could launch FFVII Remake offline, so this is yet another online-only, single-player game from Square Enix on the PC.

Hello AB2012 & pedrovay2003
I just found this list

pcgamingwiki.com/wiki/List_of_DRM-free_games_on_Epic_Games_Store

Are you aware of it? Is it trustable? How does it compare to your spreadsheet?

Please let take the opportunity to thank you for this great effort and wish you Merry Christmas :)

Thanks for letting me know. Wow Square messed up on this one.

Today's freebie Vampyr runs without the launcher.

Thanks everyone, I've caught up.

Yes I'm aware of it. PCGW is an excellent resource and I actually have an account over there and have contributed almost 300 entries. As for how they compare, there are some entries from there that I've added here and vice-versa, I know this list is referenced in several DRM-Free on Epic entries which I don't mind at all.

Thank you AB2012. Happy holidays to all the contributors & thank you all! Collaboration rocks!

Pathfinder Kingmaker runs drm-free with -EpicPortal.

can second this...tried it with wine-ge and is working as expected...no need for "-EpicPortal" or any args....
just follow the pcgaming wiki article to skip those pesky intro videos....

Mages of Mystralia can be launched directly from the executable.

On a side note, Mages of Mystralia is yet another EGS game that automatically switches to your OS language with no option to manually change it. If anyone knows the command line arguement to switch languages, I'd love to hear it so I don't have to switch OS languages every time. I tried -culture=en, -language=en and -locale=en and none of those worked...

i couldn't find the parameter, but insteed to change your OS language every time, you could do the following

create a second windows user with appropriate permissions.
login as this user and configure the locale to the language you want.
(if the user has a blank password, you will need to allow blank passwords with secpol.msc)
then create a batch file in the game directory like this:

runas /savcred /user:YourSecondUser "%~dp0Build.exe"

now you can create a shortcut to this batch file on your desktop and run your game.

Hi. I tested today's free game "Moving out".

With the command "-AUTH_PASSWORD=0 -EpicPortal" the game starts and you can play. But unfortunately, once you start the game again. The save is not kept.
